MUSIC-LEAF TURNER.

To all whom it may concern:

Be it known that I, IRA L. GooDRrcH, a citizen of the United States,residing at Cupertino, in the county of Santa Clara and State ofCalifornia, have invented new and useful Improvements in Music-LeafTurners, of which the following is a specification.

My invention relates to music-leaf turners. Its object is to provide aleaf-turning device which can be attached to any musicalinstrumen'tfsuch as a comet or a piano, and by which'the leaves areturned separately, either back or forward, by a push-key.

The invention consists of the parts and the construction and thecombination of arts, as hereinafter more fully describe and claimed,havingreference to the accompanying drawings-,in which- Figure 1 is aperspective view of the inven tion applied to themusic-rack of a piano.Fig. 2 is an elevation, partly in section,.of same. Fig. 3 is a planview of the segmental mutilated gear. Fig. 4 is a front view of thesame. p a

A represents a bed-plate which is ada ted support may be'a part of a wininstrument,

like a comet, or it may be the music-rack onv the piano. This bed-platehas a flange 2 at one end with a slot 3 and a pin 4 at the other end.The music leaf turning attachment 7 has a base B, which has a tongue ortang'part 5 to fit the slot 3 and a perforation 6 to re ceive the pin 4.A screw 7, carried by the bed-plate, is adapted to lock the attachmentin opera ive position.

The usic-leaf-turning arrangement comprises a segment 8, which ispivoted in the ase B. This segment carries three gearsegments 9, 10, and11. Each of these gears is adapted to engage successively acorresponding pinion 12, 13, and 14, which pinion operates respectiverock-shafts 15, 16, and 17. Shaft 16 is a central one and has a gear 13fixed directly to it. Gear 12 is mounted on a sleeve 18, which has anoffset arm in which the shaft 15 is brazed or otherwise made a partthereof. Gear 14 is carried by a sleeve 19, which has an ofiset arm inwhich the shaft 17 is rigidly mounted. Sleeves 18 19 are concentric withshaft 15 and all turn independently. Rock-shafts 15., 16, and 17 haverespective lateral arms 20, and the arms 20 and the vertical shafts areprovided with suitable spring-clips 21 to hold a loose sheet of music22. The segment 8 is operated by any suitable means, as the pivoted stem23, having the push-button 24. Stops 25 limit the arc of movement of thearms 20 in either direction. These stops are shown as carried by the topplate C.

When the push-button 24 is out to its farthest limit, the three arms 20will lie side side. Pushing it a. third of the way in wi I operate thegear 12 to rock the shaft 15 and turn the first sheet of musics Pushinganother third of the way in on the push-key will cause the gear 10 torock the shaft 16 and turn the second sheet, &c. Pulling out on the keyturns back each sheet of music separately. ventlon is that-any sheet canbeturned positively in either direction by reciprocating the ke -stemroperly.

anifestly there may be any desired number' of gearsegments andcorresponding pinions, sleeves, shafts, and sheet-holding means.

Havingthus described my invention, what I claim, and desire to secure byLetters Patent is 1 ;In a music-leaf turner, a suitable support, arotatable art journaled therein and provided with a p urality ofsuccessively-ar ranged segments disposed in different planes, arock-shaft provided with a pinion, a sleeve concentric with the rockshaft and turnable independently thereof 'and provided with a pinion, asecond sleeve concentric with the first sleeve and turnable independentthereof and provided with apini on, saidsleeve having ofiset arms,music-leaf-holding devices carried by said rock-shaft and said arms,said One important feature of this in-' several pinions arranged indifierent planes and engageable successively by the said segments.

.2. A music-leaf turner comprising a suitable support, a rockable part journaled therein and provided .with a plurality of succes-.sively-arranged gear-segments different planes, a plurality of pinionscoaxial wlth each other and independently turnable and 'engageable withrespective of said ear-segments, a shaft connected direct wit one ofsaid pinions, sleeves surroundin the shaft and connected with the otherpmions, said sleeves havin ofiset arms, shafts carried b said arms anarranged substantially para lel with the first-named shaft, lateralpro'ections on said several shafts, and leaf-hol ing means on saidrojections and shafts.

3. A musiceaf turner comprising a suitable support, a rockable part journaled therein and provided with a plurality of successively-arrangedgear segments in different planes, a lurality of pinons coaxial witheach other and inde endently turnable and each engageable with one ofsaid gear-segments, a shaft connected direct with one of said pinions,sleevessurrounding the shaft and connected with the other pinions, saidsleeves having offset arms, shafts carried by said arms and arrangedsubstantially parallel with the first-named shaft, lateral pro ectionson said several shafts, leaf-holding means on said projections andshafts, a push-key connected to the rockable part to rotate the same,and stop means in the path of said lateral rojections to limit therotative movement of the shafts.

4. A music-leaf turner com rising a suitable su port, a unitary rocka lepart journaled t erein and having a plurality of successively-arrangedgear-segments, said segments being dis osed in different planes and eachbeing rigi with the rockable part, a rockshaft, sleeves concentric witheach other and with the rock-shaft, said sleeves and rock-shaftindependently turnable, and said sleeves having offset arms, gears onthe shaft and on the respective sleeves engageable successivel b theear-se ments on said rockable-part, leaf-ho ding means carried by saidshaft and the arms of said sleeves, and means to limit the rotativemovement of the sleeves and shaft.

5. A music-leaf turner comprising a suitable support, a rockable partjournaled therein and having a plurality of successively-arrangedgear-segments, a rock-shaft, sleeves concentric with each other and withthe rockshaft, said sleeves and rock-shaft independently turnable, gearson the shaft and on the respective sleeves engageable successively bythe gear-segments on said rockable part, said sleeves having lateralprojections, shafts carried by said roj ections and arrangedsubstantially parallel with the first-named shaft, lateral arms onthe'several shafts, leaf-holding means on the several shaft-arms, andmeans to rock said rockable part.

6. A music-leaf turner comprising a suitable support, a rockable partjournaled therein and having a plurality of successively-arrangedgear-segments, a rock-shaft, sleeves concentric with each other and withthe rockshaft, said sleeves and rockshaft independently turnable, gearson the shaft and on the respective sleeves engageable successively bythe gear segments on said rockable part, said sleeves having lateralprojections, shafts carried by said projections and arrangedsubstantially parallel with the first named shaft, lateral arms on theseveral shafts, leaf -holding means on the several shaft-arms, stopmeans to limit the rocking movement of said arms, and a push-keyconnected to the rockable part to rotate the same.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
